90° vacuum/extraction take-off joint for seamless integration into laboratory glassware assemblies Key benefits Easy integration: 90° angled design fits neatly into common lab assemblies to redirect flow or connect vacuum/extraction lines without bending tubing or stressing glassware. Broad compatibility: External ground-glass joint accepts standard sizes 14/20, 19/22, 24/40 and 29/42, reducing the need for additional adapters. Reliable chemical resistance: Constructed from PTFE and glass to withstand common solvents and reagents while minimizing contamination. Precise flow control: 2 mm opening provides controlled throughput for reproducible extraction and transfer operations. Durable and long-lasting: Material choice and robust construction resist wear from repeated assembly and chemical exposure. Features 90° angled extraction/vacuum joint for compact, leak-minimizing connections. Compatible with external ground-glass joint sizes: 14/20, 19/22, 24/40, 29/42. PTFE and glass construction for chemical compatibility and mechanical stability. Fixed 2 mm aperture for controlled flow and extraction performance. How this product solves common lab problems Eliminates awkward tubing angles that cause strain or leaks by offering a compact 90° take-off point. Avoids frequent replacement and contamination by using chemically resistant PTFE and glass surfaces. Improves reproducibility of extraction and transfer steps through a precise 2 mm opening that limits uncontrolled splashing or variable flow. Typical applications Distillation and solvent removal: use as an angled vacuum take-off between condensers and receivers to maintain a secure vacuum connection while directing distillate flow. Controlled extraction and sampling: attach to reaction vessels or condensers when small, reproducible sample withdrawal or vapor extraction is required. Vacuum manifold and filtration setups: integrate into assemblies that need a compact, chemically resistant connection point for laboratory vacuum lines. Specifications (as provided) Angle: 90° External ground-glass joint compatibility: 14/20, 19/22, 24/40, 29/42 Materials: PTFE and glass Opening diameter: 2 mm Notes for use Match the external joint size to the mating ground-glass connector for a secure fit. Inspect PTFE seals and glass surfaces for damage before use to maintain vacuum integrity. Clean according to lab protocols appropriate for PTFE and glass to preserve chemical resistance and longevity.
